Why is Knoxville making the switch to LED?

The City of Knoxville spends approximately $4 million each year to cover the energy, operations, and maintenance costs associated with the city's approximately 29,500+ high pressure sodium (HPS) street lights. By converting these HPS lights to modern light emitting diode (LED) technology, the City anticipates achieving significant savings as a result of reduced energy consumption and reduced maintenance costs. Other benefits include:

• Improved light quality, including a reduction in light pollution and improved safety;
• Greater reliability, and fewer outages, sustained by a 10 year luminaire warranty;
• No disposal hazards;
• Greenhouse gas emissions savings, helping the City achieve its goal of reducing municipal greenhouse gas emissions 20% by 2020.


LED lights vs High Pressure Sodium lights


The City has contracted with Siemens to provide turn-key design and installation services for the LED project. The scope of work for the contract will include three phases, summarized below. Full descriptions may be found in the RFP.

1. Phase One: Project Development
a. Review and Update Streetlight Inventory
b. Complete Photometric Analysis
c. Assess Rebate Eligibility & Billing
d. Develop Initial Replacement Plan
e. Test Deployment for Stakeholder Input
f. Confirm Replacement Plan
g. Secure All Necessary Approvals

2. Phase Two: Project Implementation
a. Purchase Materials/Manage Deliveries
b. Community Outreach/Awareness
c. Obtain Traffic Control Permits
d. Installation of New Lights
e. Removal and Disposal of Old Lights
f. Inspect Work/Correct Punch List

b. Process/Receive Applicable Rebates
c. Reconcile Ongoing Billing
d. Provide As Built Documents
e. Provide 1-800 Telephone/Online Input Options

Phase 1 for the project will begin in 2017, and will include an extensive design phase that includes test/demo installations of new lights for evaluation by the City and public stakeholders. During the design phase, there will be multiple opportunities through public meetings and the demonstration installation for local residents and businesses to review and comment on the new proposed lighting. Additionally, project staff can be available to discuss the project and LED lighting plans with neighborhoods and other community groups. 

Once the design phase is complete, Siemens expects to begin installation of new lights across the city in late 2017 or early 2018. According to the contract terms, all work is expected to be complete by June 30, 2019.
